If a parameter can be configured by changing its numerical value, each digit is indi-
vidually editable. So after invoking a menu item of this kind (e.g. "DAMPING"),
pressing the S button makes the first digit of the currently set value begin to flash.
You can now use the Z button to adjust the desired digit. Now press the S button,
and the following digit begins to flash and can be adjusted as described. After you
confirm the set value by pressing the Z+S buttons simultaneously, the whole value
is saved and the display shows "OK" if the value is permitted (the menu returns to
the normal operating display after 60 s, or you can exit the menu by selecting Exit).
Otherwise an error message (e.g. ERROR VALUE) appears on the display and the
value is not saved. (Press the Z+S buttons simultaneously to return to the menu.)
If it is necessary to set a negative value, you must switch the sign using the Z but-
ton.

GET 0%
Adjusts the zero point for the output signal
After setting and applying the reference pressure (e.g. 0 bar), press the Z and S but-
tons simultaneously for at least 2 – 5 seconds in order to specify that the acting pres-
sure is to serve as the start value for the output signal (4 mA); the display then indi-
cates "OK".
This means that the specified span is shifted without any interaction; the digitally dis-
played value corresponds to 0% output signal for the acting pressure. If the digitally
displayed physical pressure is also to be corrected to zero, this must be done using the
SHIFT ZERO menu item.
The displayed value remains unchanged.
GET 100% Adjusts the end value for the output signal
After setting and applying the reference pressure (e.g. 20 bar), press the Z and S but-
tons simultaneously for at least 2 – 5 seconds in order to specify that the acting pres-
sure is to serve as the end value for the output signal (20 mA); the display then indi-
cates "OK".
The set span is changed. The zero point remains as previously set; for the 20 mA
point, the acting pressure is adopted as 20 mA or 100% of the output span.
The displayed value remains unchanged.
SET 0%
Sets the start value (as a numerical value in physical units)
Use the Z and S buttons to set the start value for the measuring range, and then con-
firm the value by pressing the Z and S buttons simultaneously for at least 2 – 5 sec-
onds. The display shows "OK".
SET 100% Sets the end value (as a numerical value in physical units)
Use the Z and S buttons to set the end value for the measuring range, and then con-
firm the value by pressing the Z and S buttons simultaneously for at least 2 – 5 sec-
onds. The display shows "OK".
